- annortann To all whom it may concern: y Be it known that I, NICK G. STAR, a citizen of the United States, residing at Cor sica, in the county of Douglas and State of. South Dakota, have invented new and useful Improvements in Aeroplanes, of which the This invention relates to improvementsin aeroplanes, the principal object of the invention being .to provide a plurality of propellers with means for moving them into ver.

tical position to raise the aeroplane off the ground and then move them into a horizontal position to drive the aeroplane horizontally through the air.

Anotherobject of the invention is to provide means for adjusting the main propeller blades to any desired pitch to suit the condition of the air or to set them at sucha pitch that the propeller will have a reverse action to act as a brake for the machine or to reverse its movement. I

. Still. another object of the invention is to provide means whereby the main propeller blades may be adjusted and the other propellers moved to either horizontal or vertical position by manually operated means located adjacentthe drivers seat. 7

This invention also consists in certain other features of construction and in-the combination and arrangement of-the several parts, to be hereinafter fully described, illustrated'in the accompanying drawings and Y s ecifically pointed out in the appended ure 5.

'c aims.

In describing m invention in detail, references will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout theseveral views, and in which Figure 1 is a plan view of the invention.

Figures 7 the connections between the hand levers and the different parts to be actuated thereby.

the aeroplane and 2 the planes thereof, these parts be ng arranged in any desired manner.

A framework 3 is suitably connected with the planes and fuselage and this frame supports a plurality of brackets 4; in which the framework for the swinging propellers are supported. Each of these swinging propellers consists of an oil tight casing 5 which is provided with the hollow bearings 6 which engage openings formed in the bracket so that said casin is swingingly supported in the bracket- 11 open framework .is seconnected the propeller blades 9. This shaft 8 is suitablyjournaled in-the top of the easing' and has its end extendingr-into-said casing andthisend carries thebeveled gear 10 which meshes with a gear 11 carried by the shaft 12 which, passes-through the hollow bearings 6 of the housing and is suitably journaled therein. These parts are provided with suitable packing means for preventing the oil within the casing from escaping. Y H 4 Y As will be seen the propeller supporting frames are arranged inpairs with a shaft 12 for each pair, though one 'oftheshafts en-- gages one of these pairs. It will of'course be understood however, that these propeller "supporting frames and the .shafts maybe arranged in .any' desired manner. These shafts 12 "extend transversely across the aeroplane'andadjacent each of the supporting frames I provide anniversal joint 13 for permitting acer'tain amount of movement of the outer parts of, each shaft. The

shafts are connected w ith each other by the longitudinally extending shafts-14 and the gears 15,,said gearsbeing' enclosed in casings 16 so that said gearsmay rotate in lubricant.- These shafts 14- are also providedwith uni-' versal joints 14:.- The long shaft 12' which engages the twopairs of propeller supporting frames carries'the gear 17 which meshes with the gear 18 on one of the shafts 14 and with a gear 19 which is located on the clutch.

shaft 20', these gears being located in the clutch is moved into operative position all the transverse shafts will be rotated 'so asto drive the propellers 9. The clutchis actuated from a point-adjacent the driverS 25 to hold said frames in adjusted position.

links 25.

adjacent the drivers seat.

provided with a hand wheel 33 by means 'ber 40 and the stems ll of the blades are seat by the hand lever 24 and the connecting -The means for moving the propeller sup porting frames into horizontal or vertical positions comprises a transverselyarranged shaft 26 which is provided with the arms 27, said arms being connected with the brackets 28, which are secured to the propeller supporting frames, by the links 29. Thus when the shaft 26 is rocked said supporting frames will be raised and lowered to vertical and horizontal positions so that the propellersmay be used for raising the aeroplane or for driving the same horizontally. This shaft 26 .is provided with a gear wheel 30 which meshes with a wheel 31 located on a short shaft 32 mounted in the fuselage This shaft is of which it may be rotated. This shaft is also provided with a brake drum .34 the brake band 35 of which is connected by the links,3 .6 with the hand lever 37 so that. after the wheel is turned to position the propeller frames the brake can be applied The main propeller comprises the two blades 38 and the hub 39, said hub'being connected with the'engine shaft in the usual manner. This hub isprovided with a chamrotatably mounted in ,the hub and project within this chamber and the ends 0 these stems carry the small gears 41' which. are

vwith said hub. This collar is provi, ed wit engaged by the rack bars 42. which are slidably mounted'in the hub and have portions extending therefrom. These extend-' ing portions of the rack bars are connected by the pinions-4=3 with'the collar 44:, slidably mounted in a part of the huband rotatin an annular groove in-which is-located a ring member 45 which is connected w'ithfthe yoke 46. Ball bearings 47 areplaced between the ring member 45 and thewalls of the groove.

A lever 48 is pivotedintermediate its ends to the bracket 49 and one end of thisleveris connected with the yoke 46 and its other end is connected with the rod 50 which is connected with the hand lever' 51. It will thus be .seen'that by manipulating the hand lever the'collar will be moved on'the inner;

part of the hub to reciprocate therackbars so as to rotate the pinions 41 and thus adjust the pitch ofthe blades 38, By this arrange-v ment of parts the pitch of the main propeller blades may-be'adjusted to suit thecondition of the air or'they maybe so adjusted as to and then gradually rising.

' 10 It is thought from the foregoing descrip-' tion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction. and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is V V 1.-In an aeroplane, a pair. of brackets forming a part of the framework thereof,

a casing havlng'a pair of hollow bearings which are rotatably supported by said brackets, a shaft passing through the' hollow bearings and the casing, an open framework supportedby the casing, a propeller shaft journaled in said framework and extending into the casing, gears located inJthe casing for connecting the two. shafts together, a propeller on the ropeller shaft, a bracket connected with t e open framework and manually operated means-connected with the bracket for moving the casing in its supportpropeller into v'ering brackets to move the tical or horizontal position.

2. In an aeroplane, a plurality of pairs of brackets forming partif the framework thereof, an oil tight casi g having hollow bearings which are rotatably mounted in each pair of brackets, a plurality of transverse shafts extendingthrough the hollow bearings and the casin means for rotating said shafts, an" open ramework supported by each casin a propeller shaft journaled in each open ramework and extending into thecasing, gears in each casing for connecting the propeller shaft with its drive shaft, a bracket connected with each open framework and manually operated means connected with each bracket for moving the parts to cause the casings to rock in the brackets to move the propellers into horizontal or vertical position.

In testimony whereof I aflix my signature.
